Example: Changing Model Geometry in Parts Containing COM and COMR Points

This example demonstrates how the locations of the Center of Mass (COM) point and a Center of Mass Reference (COMR) point are influenced by various changes in the geometry of a part.

  1. Add a COM point to a part.

  2. Create a COMR point.
    Because they are coincident, the COMR point COM_reference_point_feature_GA.gif is hidden behind the COM point center_of_mass_feature.gif. Only the + from the COMR icon is visible.

  3. Add a new feature to the part.
    The COM point center_of_mass_feature.gif moves to the new center of mass of the model. The COMR point COM_reference_point_feature_GA.gif remains where you created it.

  4. Modify the tab features that already existed before you created the COMR point.
    The COMR point COM_reference_point_feature_GA.gif moves to the new center of mass of the tab features. The COM point center_of_mass_feature.gif moves to the new center of mass of the entire model.
